摘　　要：介绍了配套固相增黏装置的前期PET装置中切粒系统传统工艺流程,指出其运行期间存在的问题,提出了用BKG结晶切代替传统切粒机的改造方案,对改造前后的节能效益进行了比较。The traditional technological process of pelletizing system in first-phase PET plant which match to the sol- id state polycondensation was introduced. The existing problems during its operation were pointed out. The transfor- mation scheme that using BKG crystall cut instead of traditional granulator was proposed. The energy efficiency pre- and post-transformation was compared.
